共享经济行业可持续性评价的社会感知和客观绩效不一致将造成认知错位、投资误判和政策失效等结果。本文在线挖掘2017—2019年我国主要社交媒体上29 771条文本信息,并收集行业统计数据,综合测度共享经济行业的可持续性并比较其差异。研究发现:社会公众并不认为共享经济行业具有显著的总体可持续性,而且行业实际绩效展现的可持续性与社会大众认知截然不同。进一步发现:受限于主观认知能力,社会公众认为共享经济可持续性主要来自可观察到的行业外部经济和外部生态等维度,但客观绩效表明共享经济行业内部的经济和外部的技术优势才是其可持续性的重要支撑。此外,二者评价的差异在住宿与医疗等产能共享内部过程不易被大众观察的行业中最为突出。 相似文献

《中华人民共和国食品安全法》的修订和国务院机构改革,进一步理顺了食品安全监管关系,明确了食品安全面临的监管问题,从多方面、深层次强化了我国的食品安全监管制度,但层出不穷的食品安全事件表明,食品安全制度和监管层面的改革在广度和深度上仍有欠缺,体制机制依旧存在障碍并且亟待破除。食品安全法律规制不仅应通过立法技术填补法律漏洞、协调监管冲突,还应运用食品安全规制技术进行风险评估模式的革新,推动构建食品安全规制主体的多元化协同治理体制。 相似文献

绿色创新是我国实现经济社会绿色转型的必然要求,企业绿色创新决策与社会责任水平存在关联,供应链中社会责任承担主体差异将影响企业绿色创新决策。构建一个二级供应链模型,考察承担主体差异对制造商绿色创新决策的作用机制,探究各影响因素对决策结果的影响,研究发现:供应链主体社会责任承担情况将影响制造商绿色创新,各方社会责任分担比例与各情形下绿色创新投入、双方效用正向相关;制造商与零售商双方共担社会责任下的绿色创新水平将优于单方承担社会责任情形,两类单方承担情形下的绿色创新水平大小关系与双方社会责任承担比例间的数量关系有关;消费者绿色偏好与制造商绿色创新投入、双方效用、零售价格与批发价格正向关联,消费者价格敏感度则与上述变量反向关联。提出相关策略建议,以期为供应链企业绿色创新促进提供有益参考。 相似文献

This paper explores whether high-school sports are functional and accessible activities to keep students from school disciplinary behaviors. For this purpose, we included students racial and linguistic status, socioeconomic status, sex, and prior academic performance with the school’s proportion of free-lunch recipients and minorities, to understand how sport participation affects students of diverse groups. Additionally, the study implemented a multilevel mediation modeling to the Education Longitudinal Study (ELS) data and assessed student dropouts with sequential mediators of sport participation, school misbehavior, and suspension. The findings of the study largely revealed that White students participated in sports more than Black, Hispanic, and Asian. Likewise, students who speak English as the primary language and male students participated in sports more than their counterparts. White sport participants displayed fewer incidents of suspension than White non-sport participants. Black, Hispanic, and White sport participants had lower dropout incidents than their non-sport-participating counterparts. 相似文献

Primary–secondary school transition encompasses multiple social, academic and environmental changes which can negatively impact children’s emotional well-being. Children with Social, Emotional and Mental Health difficulties (SEMH) are believed to be especially vulnerable during this time. However, the voices of children with SEMH are heavily underrepresented in this field within practice and research. The present case study examined how children with SEMH difficulties within one special school experience primary–secondary school transition and how they are supported, in order to make recommendations to improve this period. The case study was qualitative and longitudinal, conducted over 18-months and methodologies included ethnographic observations, child photo-elicitation focus groups (with 11 Year 6 children) and three adult interviews. Findings demonstrated that over primary–secondary school transition children with SEMH difficulties (a) negotiate significant structural changes in support (often unanticipated) and (b) need to feel a sense of safety and belonging. To manage this effectively, transition provision for children with SEMH difficulties needs to consider their short-term emotional well-being whilst still in primary school, in addition to their long-term well-being looking ahead to secondary school. Greater collaboration and communication across schools and stakeholders can help ensure children receive continuity in standards and support. 相似文献

This article analyses leadership in the newsroom of the Spanish newspaper El País as well as its impact on the craft of journalism more generally. Through 23 in-depth interviews, we try to elucidate how the newsroom constructs its leaders (in the newsroom, what does it mean to be a leader?), paying particular attention to the main skills considered to be necessary. According to our newsroom findings, not all heads of section or editors-in-chief are leaders, a fact that questions formal authority relations and proclaims expertise and know-how as discriminatory skills. This study emphasizes that the collective recognition of a leader is not an ultimate disposition, but can vary over time: consequently leaders who do not achieve the professional requirements of the newsroom can be denied the status, despite their expertise and experience. Our findings indicate that leaders at El País are those journalists (no matter what their positions) with strong capacities and skills (fundamentally experience, expertise and creativity) to manage form (relationships) and substance (contents) in the daily work of the newsroom. In short, journalists seen as leaders combine reiterated and strong qualities and merit, graphically reflected in the texts they have published for years in the newspaper. 相似文献

AbstractThis study examined a project that delivered social work services to homeless individuals. A mixed-methods case study was conducted using quantitative and qualitative data from 93 library employees and the project’s Homelessness Prevention Outreach Worker (HPOW). There was an increase in the number of clients accessing community supports during the project, and the HPOW was integral to the provision of support and resources to homeless individuals. Staff training was associated with significantly greater knowledge, comfort, and skills in working with homeless individuals. These findings can inform the delivery and implementation of similar programs for homeless individuals. 相似文献
